IMPROVEMENT IN POTATO-DIGGERS.

Specification forming part of Letters Patent No. 25,721, dated October11, 1859.

To all whom it may concern:

Be it known that we, A. S. OAPRON and D. S. DAVIs,of Grass Lake,in thecounty ofJackson and State of Michiga nhave invented certain new anduseful Improvements in Potato-- Diggers; and we do hereby declare thatthe following is a full, clear, and exact description of the same,reference being bad to the accompanying drawings, and to the letters ofreference marked thereon. v

The nature of our invention consists in urranging the several parts ofthe machine together substantiallyi-i the manner hereinafter described.

In the drawings, Figure 1 represents a longitudinal section. Fig. 2represents a bottom view.

In the figures, A A represent two wheels, which are secured in the usualmanner upon an axle, B. G represents a smaller wheel, secured to one ofthe wheels A, said wheel 0 being provided with cog-gearing on its innerrim E represents a crank-shalt, which is supported in bearings h h h. Toone end of this crank-shaft there is attached a pinion, which works inthe gearing upon wheel U.

D represents arake, which is secured to the handle d, said handle beingsecured at one end to the crank on shaft E. The handle (1 passes betweentwo guides, c e, and rests upon aroller, or, which is secured betweensaid guides.

H represents an apron, which is connected to the axle B by means of twolong hooks, i i. This apron drags upon the ground behind the machine inbut front of the rake.

\Vhen this machine is set in motion the wheel 0 communicates motion tothepinion F, the crank-shaft E, and thence to the rake D. It will beseen that the handle of the rake resting upon the roller 00, andoperated by means of the crank on shaft E, the rake will have a motiongiven to it similar to the movement of the ordinary hand-rake. It willbe dragged along on the ground,-then raised and pushed back, and thendragged along on the ground again. The apron being in the shape of theblade of a com mon shovel-plow, when the rake draws the potatoes uptoward and upon the apron they fall off on each side of said apron. Therake each time it is pushed back commences to rake at about the point itleft ott' when it was raised by the crank.

This machine, it will be seen, rakes the potatoes from the furrow and,freeing them from the dirt, distributes them on each side of the furrowand of the apron.

Having thus fully described our invention, what we claim as new, anddesire to secure by Letters Patent, is-

The arrangement of axle B, wheels A A,

and wheel (J, pinion F, crank-shaft E, guides e c, roller 90, rake D,apron H, and books 2' i, the whole being'connected together andoperating snbstai'nially as and for the purpose specified.
